This happened to me while installing a game (hedgewars). Apport kept popping up windows with "Sorry Software center closed unexpectedly" at for each new item in the software list I selected. Note that software-center did not really close in this interval (I was even able to install other software in the same seession, just Apport kept telling me stuff was not alright).
** Changed in: software-center (Ubuntu) Status: New => Confirmed -- software-center crashed with AttributeError in do_render() https://bugs.launchpad.net/bugs/523341 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
